Abstract

In the injector provided especially for flotation devices, the liquid, especially suspension, is mixed with sucked-in air in a mixing zone which is provided essentially in a straight tube (2). The liquid is previously subjected to turbulence by means of a diaphragm (3), the diaphragm being a perforated disc with a multiple, preferably symmetrical hole arrangement. <IMAGE>
